DIY spray foam?

There is a kit (several) from Amazon. Has anyone used these kits? How did it work out? Do you have any recommendations?
TIA

You need to be more specific. What's it for?
I jes bought some expandable foam to fill in the indentations in my siding (forget the name of the siding) to keep wasps out. Haven't used it yet, but only a single can (Great Stuff Big Gap FIller).

Amazing how people can ask questions with no info to go on. I would guess that he's probably talking about something more involved than a can of spray foam, since he said "kit". Like maybe it's intended to be the DIY version of the pro stuff that they use to fill wall cavities, etc. But who knows.. And I'd say it's probably 80% that we'll never find out.

I was excited. I thought I was going to learn how to make the foam.

Sorry about that. I hold conversations in my head and forget to write things down outside my head. :)
This is a 600 board feet kit (about $600 at Amazon). My intention is first to spray insulation between two roofs in an external, detached building I'm performing maintenance and converting to an "efficiency apartment". The second task, later, would be to spray the foam insulation inside the structure between the non-structural framing members. Once the inside is complete and cured I plan to use Great Stuff to fill cracks from the outside. Once the Great Stuff is cured I plan to apply a plaster/stucco mix to the outside to seal the exterior. After the plaster/stucco I will paint the exterior.
The original application between the roofs will be closed foam and should be about 1" thick. My idea is to seal the original roof and insulate. I am considering getting a second kit to apply a second inch, for a total of two inches, and to make sure everything is sealed before the second roof (gable) is replaced and sealed.

Not a secret. There are a few I'm looking at:

I mentally planned on the first link. Just now I see there's an additional $115 for shipping.

Mike, DIY spray foam kits are costly but invaluable for irregular surfaces. I fo llowed this guy's recommendation for my retrofit and I'm happy with results and it was much cheaper than spray foam, but is only good for consistent, open areas that you can fit cut boards into (i.e. not crazy irregular surfa ces and spaces).

P.S. for roofs, don't forget to consider leaving an air gap if you have fun ctional soffit and ridge vents!

IF you have irregular surfaces or spaces, spray foam is a costly necessity. But if you have consistent, even spaces, consider using board insulation cut to size, and spray foam can around perimeter, like this example:

Saves money over spray foam.
Also, if you're doing a ceiling against the roof, remember to consider leaving an airspace if you have functional soffit and ridge vents.

I understand you have to be very careful to follow the instructions exactly. If you don't it can wind up making your home unhealthy. You might want to do a web search to check and see how other people have done.
I checked on the web a couple of years ago when I saw somebody pushing their service at a home show.

I used TigerFoam to insulate under the floor in a cold corner of the house. It's not a walk in the park to apply, and you have to follow the instructions exactly, but it does work.

Like Arthur Conan Doyle, we used TigerFoam. Two canisters that looked a bit like propane grill tanks, hoses, mixing nozzles, everything we needed.
We insulated our crawlspace and a few other areas on the first occasion, and then we used another batch to insulate the hot tub we built from a kit. Clearly, since we used it twice, we liked how it worked the first time.
Follow the instructions meticulously, and don't be afraid to switch to a new nozzle any time. Buy a few extra nozzles, just in case. If the mixing doesn't happen correctly, the foam won't cure properly.

Artie!! How goes it man? Long time no see!
Glad I ran into you because I just finished reading one of your Sherlock stories and have a guestion I've been wanting to ask you. It's about the rather singular relationship between Holmes and Watson. I know that somewhere along the story line Watson get married, but his wife dies after a few years of happy marriage. Then it's back to that singular relationship with Holmes again.
It's clear their relationship is "special", but how special? To me it seems very, very special indeed.
Also, when mixing his 7% solution what does Holmes use for dilution? I'm assuming water but you never say.
Take care Artie. Keep up the good work.
